SPECIFICATION forming part' of Lettere Patent No. 611,825, aerea oeteber4, 1898.

Applieetien feed Mey z5, 1398.;

ToaZZ whom it may concern:

Beit known that I, JOHN H. VoLKMANN,re siding in the city, county, andState of New York, have invented certain new and useful Improvements inCoin-Testers for Coin-Controlled Apparatus, of which the following' is aspecification.

My invention relates to coin-testers for coincontrolled apparatus, suchas vendingmachines, and the invention is in the nature of an improvementupon the device forming the subjectmatter of my former patent, No.A483,188, which was issued to me ou the 27th day of September, 1892. Y

The object of my present invention is to render the device of my formerpatent above referred to and coin-testers generally more efficient andto provide a device which will more effectively prevent telegraphingthatis to say, which will effectively prevent a washer or like false tokenfrom being rapidly projected through the tester Without allowing theparts to operate upon the token to prevent it from passing to thedelivery mechanism.

To this end my invention consists in the novel arrangement andcombination of parts hereinafter described and claimed.

In the accompanying drawings, wherein like reference characters indicatecorresponding parts in the various views, Figure 1 is a side view of acoin-tester embodying my invention. Fig. 2 is a like View of the samelooking from the opposite side. Fig. 3 is a transverse verticalsectional view of the same on the line 3 3 of Fig.. 2 looking in thedirection of the arrow. In this iigure the parts are shown in the normalposition. Fi g.` 4 is a View corresponding to Fig.,3, except that theparts are shown in the position 'in which the washer or false token isdischarged from the device. Fig. 5 is a front View of the device withthe parts shown in dotted lines to the rear of the slot-plate or theplate which is provided with the coin-receiving openings.

It should first be pointed out that the cointester herein shownconstitutes in a sense a portion of a coin-chute, so that the coin inits passage from the coin-inlet or slot-opening of the apparatus to thedelivery mechanism must pass through the coin-tester. It is' immaterialfor the purposes of my invention what Serial No. 681,6 5 5. (No model.)

character of delivery or operating mechanism isv used, inasmuch as thecoin-tester may be employed with any character of coin-controlledapparatus, and hence I have shown no delivery or operating mechanism.

In the drawings, A represents the framing, which supports one or morecoin-testers in an inclined position in the machine, as indicated in thedrawings, and I prefer to make the slots or coin-receiving openings c ofeach of these coin-testers in the front plate b of this framing. To thisframing is secured a stationary plate B,which is provided at its loweredge with a coin-track c, that is cutaway or recessed for a portion ofits length, as indicated at d, for the purpose of allowing a coin ortoken of less thickness than that intended to operate the apparatus topass through the recess to a point where the token is ineffective tooperate the delivery mechanism. A movable plate C is pivoted to thestationary plate by a pivot-pin c or otherwise. The movable plate C isnormally maintained in contact with the track c, as illustrated in Figs.

3 and. 5, by a spring f, which is shown to pass around the pivot c, andone end of said 'spring bears against the upper edge of the movableplate, while theV other end rests against a stationary portion ofthestructure. The movable plate C is provided with an elongatedperforation, as indicated at g, for the purpose of allowing a coin ofsmaller diameter than lthat intended to` operate the device to drop othe track to one side and to a point where it is ineffective to operatethe delivery mechanism. The movable plate C is likewise provided with afinger 0c, which is located adjacent to the front plate b and projectsacross the slot at the upper portion thereof, as clearly l indicated inFig. 5, so that when a coin of the requisite diameter is inserted in theslot the coin will contact with the finger and will force the movableplate O around its pivot into the position indicated in Fig. 4. Thisseparation of the platesB and C allows any false coin or token which mayhave been prevented passing through` the tester to be discharged into asuitable receptacle, where it is ineffective to operate the.delivery-machine. To one of the plates B C (to the plate B in thepresent instance) a magnet D is secured by means of a support F, whichis pivoted in any IOO suitable manner, as indicated at h, and ismaintained in the normal position represented in Fig. 3 by a spring y. Alink connection t' unites the pivoted supportF of the magnet with theopposite plate, so that a movement of the plates away from each otherwill cause the magnet to be moved around its pivot, so as to convey thepoles of the magnet out of the path of the coin or from their positionadjacent to the coin-passage.

Pivoted to the pin e is a washer-catcher E, which in the presentinstance is normally maintained in the position illustrated in Fig. 3 byits own weight. It will be observed that the washer-catcher extends tothe rear of the magnet D and in the path of the movement thereof, sothat when the magnet is vibrated from the position shown in Fig. 3 tothat illustrated in Fig. 4 it will contact with said washer-catcher andpositively move it to one side for purposes which will hereinafterappear. When the washer-catcher is in the position illustrated in Fig.3, the free hooked ends k Z thereof project across the path of the coinin its passage through the tester. These hooks 7i; Z project toward eachother, so that a coin such as is intended to be used in the instrumentwill force the washer-catcher out of its path and the coin is free topass to the delivery mechanism. It', however, a Washer of the thicknessand diameter of the coin intended to be used is inserted in the slot, itwill be caught upon a hook 7c and will be prevented from passing throughthe tester. When the next coin or token is inserted in the slot d, theplates B C will be separated in the manner hereinbefore described,whichwill result in the magnet being vibrated on its pivot, thereby movingthe washer-catcher to the position indicated in Fig. 4, which causes thehook-like projection 7c to be withdrawn from the perforation in thewasher, and the plates being separated. at this instant the washer isallowed to drop from between them.

It has been found in practice that when a washer is projected with someforce through the coin-tester the gravity washer-catcher will bevibrated to its fullest limit out of the path of the washer and that itdoes not always drop back into position in time to allow the hook 7c toenter the perforation in the washer and prevent it from passing to thedelivery mechanism. The principal object of the present invention is toprevent a washer from being projected rapidly through the device tooperate the delivery mechanism. For this purpose I provide an abutmentm, which is adapted to be moved by the operation of the movable plate C.In the present instance this abutment m is in the nature of a nger whichprojects from the vibratory magnetsupport F and in the normal positionextends back of the washer-catcher, as indicated in Fig. 3, and is justfar enough away from the catcher to allow it to clear itself from thepath of the coin. Vhen, however, the plates B C are separated by theinsertion of a coin,

the stop m is automatically moved out of the path of the Washer-catcherto allow a full and free movement thereof, as indicated in Fig. 4. Bythis means it will be understood that should an attempt be made totelegraph the device the washer-catcher, after it has moved sufficientlyfar to clear the first hook l, will strike against the abutment m, andthe catcher will immediately be in a position where the hook 7c thereofwill drop into the central opening in the washer and prevent a furthermovement thereof along the chute formed by the plates B C. The morerapidly the washer is projected through the tester the more rapidly willthe washer-catcher return to the engaging position because of the factthat it strikes with greater force against the abutment m.

From the foregoing description it is thought that the operation of theapparatus will be understood and that no further description of theoperation is required.

In practice my improvements have proven simple, cheap, and eflicientmeans for overcoming the difficulties hereinbefore pointed out.

While I have shown and described my improvements in a coin-testingdevice embracing features which are disclosed in patents heretoforegranted me, I would have it un derstood that the device forming thesubjectmatter of my present invention may be employed in anycoin-testing apparatus where it may be found available.

lVhat I claim, and desire to secure by Letters Patent, is-

l. In a coin-tester, the combination of a vibratory washer-catchernormally projecting across the path of the coin and an abutment againstwhich said washer-catcher is adapted to be forced by the coin in itspassage through the tester.

2. In a coin-tester, the combination of a vibratory washer-catchernormally projecting across the path of the coin and a movable abutmentagainst which said washer-catcher is adapted to be forced by the coin inits passage through the tester.
